Abstract (en)
[origin: EP0391153A2] A method for recording and reproducing a radiation image comprising the steps of (i) causing a visible or infrared radiation stimulable phosphor to absorb a high-energy radiation passing through an object, (ii) stimulating said phosphor with visible or infrared radiation to release the stored energy as fluorescent light and (iii) detecting said fluorescent light with light detecting means, is characterized by the fact that the photostimulable phosphor is selected within the group of rare earth orthosilicates activated with a first activator comprising cerium and/or terbium and a second activator comprising zirconium and/or samarium, wherein rare earth is one of a) yttrium, b) yttrium and lutetium and c) yttrium, lutetium and gadolinium. Panel for storing a radiation image containing the above described photostimulable phosphors. Phosphors selected within the group of rare earth orthosilicates activated with a first activator comprising certium and/or terbium and a second activator comprising zirconium and/or samarium, wherein rare earth is one of a) yttrium, b) yttrium and lutetium and c) yttrium, lutetium and gadolinium.
